| 摘 要： | 青鱼、草鱼、鲢、鳙统称为四大家鱼,长江中游河段是其最主要的产卵场.近年来,水利工程的建设和运行,对四大家鱼产卵场的范围和质量造成一定的影响.产卵场的恶化主要影响家鱼的繁殖,通过分析四大家鱼的繁殖特性,识别出影响家鱼产卵和孵化的关键生态因子,并建立了各生态因子的适宜度曲线.建立四大家鱼栖息地适宜度方程,对家鱼产卵场进行综合影响评价.用实测资料对方程进行验证,结果表明方程能较合理地描述四大家鱼栖息地的适合程度.

| Abstract: | Dam construction and river training projects are changing the river environment and stream habitat.The four species of carps in the Yangtze River have the most important fresh water fishery in China.They are black carp(Mylopharyngodon piceus),grass carp(Ctenop haryngodon idellus),silver carp(Hypoph thal michthys molitrix)and big-head carp(Aristichyths nobilis),which are the four major Chinese carp species.The habitat of these carps in the Yangtze River were seriously influenced by the construction and opera... |
